Blueberry Cream Cheese Croissant Casserole (Printable)

Buttery croissants baked with creamy cheesecake filling and bursts of fresh blueberries for an indulgent morning treat.

# What You'll Need:

→ Croissant Base

01 - 5 to 6 large buttery croissants, preferably day-old (about 12 oz), cut into 2-inch pieces

→ Berry Layer

02 - 1 1/2 cups (about 8 oz) fresh or frozen blueberries

→ Cream Cheese Mixture

03 - 8 oz cream cheese, softened
04 - 1/3 cup granulated sugar
05 - 2 large eggs
06 - 2/3 cup whole milk
07 - 1/3 cup heavy cream
08 - 1 teaspoon vanilla extract
09 - Zest of 1 lemon (optional)

→ Topping

10 - 1 tablespoon turbinado sugar or granulated sugar (optional, for crunch)
11 - Powdered sugar, for dusting (optional)

# Method:

01 - Preheat the oven to 350°F. Grease a 9x13-inch baking dish with butter or nonstick spray.
02 - Scatter the croissant pieces evenly across the bottom of the prepared dish. Sprinkle the blueberries in an even layer over the croissants.
03 - In a large mixing bowl, beat the softened cream cheese and granulated sugar together using an electric mixer or whisk until smooth and creamy.
04 - Add the eggs, whole milk, heavy cream, vanilla extract, and lemon zest if using. Whisk until the mixture is completely smooth and well combined.
05 - Pour the cream cheese custard evenly over the croissant and blueberry layers. Gently press the croissant pieces down with a spatula so they absorb the custard mixture.
06 - If desired, sprinkle 1 tablespoon of turbinado or granulated sugar over the top for a golden, crunchy finish.
07 - Bake uncovered for 40 to 45 minutes, or until the center is firmly set and the top is golden brown.
08 - Remove from the oven and let the casserole rest for 10 to 15 minutes before slicing. Dust with powdered sugar if desired and serve warm or at room temperature.

# Insider Tips:

01 -
  • The cream cheese custard seeps into every layer of flaky croissant so each bite is simultaneously crunchy and velvety soft.
  • It comes together with barely fifteen minutes of hands on work which means you can chat with your guests instead of being chained to the stove.
  • Frozen blueberries perform just as beautifully as fresh ones so you can make this year round without hunting for seasonal fruit.
02 -
  • Do not skip pressing the croissants into the custard or the top pieces will dry out while the bottom ones turn soggy.
  • If using frozen blueberries the casserole may need an extra five minutes in the oven to fully set in the center.
  • You can assemble the entire dish the night before and simply bake it fresh in the morning which is a lifesaver for holiday hosting.
03 -
  • Tear the croissants by hand instead of cutting them with a knife because ragged edges soak up more custard and create better texture.
  • A dusting of powdered sugar right before serving hides any cracks or imperfections and makes every slice look bakery worthy.
